Hi
Fuse 18 (I think) is marked as 25a fuse Trailer in the fuse box. Currently the other end (ISO connection in bumper vent) has nothing connected with just a standard 12n connection.
Did Mercedes give any specification on this circuit which they deliberately included for 12v trailer use...
We need to get a 12S socket added to our E320 estate - is there anything unusual about the wiring on a '94 model to bear in mind when getting it fitted???
Thanks.
